    Seam 2.2 injection problem in RestEasy Service

    Konrad Balabuch Newbie

      Hi,
      I have a problem with seam injection while using it in REST exposed class.
      REST works fine - itself.
      Injection works great in other components, but when component is configured to be a REST service injection returns null.
      I believe it's configuration issue, but have no idea how to make it working... could anyone help me please.
      below are my settings:


      0) I use Seam 2.2.0.GA and jBoss 5.1.0.GA but i did try it already on Seam 2.2.2.Final and jBoss6.0.Final and behavior is the same.


      1)I use EAR deployment and have attached RESTEasy jars:
      deployed-jars-ear.list:


      #WEbservices
      jaxrs-api-2.2.0.GA.jar
      resteasy-jaxrs-2.2.0.GA.jar
      
      resteasy-atom-provider-2.2.0.GA.jar
      resteasy-jaxb-provider-2.2.0.GA.jar
      resteasy-jettison-provider-2.2.0.GA.jar
      scannotation-1.0.3.jar
      
      slf4j-api.jar



      deployed-jars-war.list:



      #RestEasy
      
      jboss-seam-resteasy-2.2.0.GA.jar
      



      2)web.xml:



          <listener>
              <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
          </listener>
      
      
          <servlet>
              <servlet-name>Resteasy</servlet-name>
              <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
                <init-param>
                     <param-name>javax.ws.rs.Application</param-name>
                     <param-value>com.myApp.webservice.MobileApplication</param-value>
                      
                </init-param>        
          </servlet>
           <servlet-mapping>
                <servlet-name>Resteasy</servlet-name>
                <url-pattern>/mobile/*</url-pattern>
           </servlet-mapping>
      
           <context-param>
               <param-name>resteasy.servlet.mapping.prefix</param-name>
               <param-value>mobile</param-value>
          </context-param> 



      3)com.myApp.webservice.MobileApplication:




      import java.util.HashSet;
      import java.util.Set;
      import javax.ws.rs.core.Application;
      
      public class MobileApplication extends Application{
           
      private Set<Object> singletons = new HashSet();
      private Set<Class<?>> empty = new HashSet();
      
           public MobileApplication() {
                // ADD YOUR RESTFUL RESOURCES HERE
                this.singletons.add(new HelloWorld());
                this.singletons.add(new TestWS());
                
                this.singletons.add(new DivingLogRest());//DivingLog/{id}
           
           }
            
           public Set<Class<?>> getClasses()
           {
                return this.empty;
           }
            
           public Set<Object> getSingletons()
           {
                return this.singletons;
           }
      }
      


      4) and service class itself:



      @Name("divingLogRest")
      @Path("divingLog")
      @Scope(ScopeType.STATELESS)
      public class DivingLogRest {
      
           @In(create=true)
           DivingLogHome divingLogHome;
           
           
           @GET
           @Path("{id}")
           //@Produces({"application/xml"})
           @Produces("text/plain")
           public String getDivingLog(@PathParam("id") int id) {
                     //Logger Log log doesn't inject neither
                     System.out.println("getDivingLog called. id="+id);
                
                     System.out.println("divingLogHome:"+divingLogHome);
                divingLogHome.setDivingLogId(id);
                     System.out.println("divingLogHome:"+divingLogHome);
                divingLogHome.wire();
                
                
                return divingLogHome.getInstance().getDescription();
           }
      


      the return on the console is



      11:00:52,433 INFO  [ServletContainerDispatcher] Deploying javax.ws.rs.core.Application: class com.myApp.webservice.MobileApplication
      11:00:52,433 INFO  [ServletContainerDispatcher] Adding singleton resource com.myApp.webservice.DivingLogRest from Application javax.ws.rs.core.Application
      11:00:52,433 INFO  [ServletContainerDispatcher] Adding singleton resource com.myApp.webservice.TestWS from Application javax.ws.rs.core.Application
      11:00:52,448 INFO  [ServletContainerDispatcher] Adding singleton resource com.myApp.webservice.HelloWorld from Application javax.ws.rs.core.Application
      11:01:25,286 INFO  [STDOUT] getDivingLog called. id=1
      11:01:25,286 INFO  [STDOUT] divingLogHome:null



      Any suggestions will be appreciated! I'm stacked for a log time with this isue...
